Check out Bil’s page, KillSwitchAdvisory. Thanks to our show sponsor, ThreatLocker Alert fatigue, false positives, analyst burnout—you know the drill. What if you could stop threats before they run? ThreatLocker gives CISOs what they’ve been asking for: real control at the execution layer. Only approved apps, scripts, and executables run. Period. Known-good is enforced. Everything else? Denied by default. Ringfencing and storage control keep even trusted tools in their lane—so PowerShell doesn’t become a weapon. And yes—it works at scale. Granular policies. Fast rollout. Built for modern infrastructure. You don’t need more alerts. You need fewer chances for malware to make a move. ThreatLocker helps you flip the model—from detect-and-respond… to deny-and-verify. Go to ThreatLocker.com/CISO to schedule your free demo and close the last gap in your Zero Trust strategy, before it’s exploited.
